MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application led October 11, 1915. Serial No. 55,280.

To @ZZ whom t may cof/wem:

Be it known that I, FERDINAND G. HENRY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented lo will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to mechanical movements and has for an object to provide a mechanical movement especially adapted though not restricted to use in connection with a shoe polishing machine.

A further object of the invention is to provide new and improved-mechanical means for operating several independent parts from several independent movements.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings: Figure 1 is a view of the mechanical movement in side elevation shown in inoperative position and connected with moving parts shown conventionally. Fig. 2 is a view of the movement in side elevation shown in normal or inoperative position with dotted lines showing the first movement. Fig. 3 is a view in side elevation showing in full lines the normal or inoperative position and showing in dotted lines the second movement. Fig. 4 is a view of the movement in side elevation showing in full lines the normal or inoperative position and in dotted lines the third or final movement.

Like characters of reference designate corresponding p'arts throughout the several views.

The improved mechanical movement which forms the subject-matter of this application is adapted for use in any position or in conjunction with any machine where its peculiar type of movement is found desirable. As illustrated in 'the drawings parts of a shoe-blacking machine are shown conventionally. The parts of the machine as shown are a frame 10, a foot clamp 11 pivoted to the frame 10, an arm 12 adapted to carry cloth polishers and also pivoted to the frame 10 and a roller 13 which is supposed to be carried by and reciprocate with a carriage.

To the frame 104 is also pivoted a lever 14 which is in the path of the movement of the roller 13 and is oscillated by each reciprocation of such roller. It is assumed that the roller 13 reciprocates with a carriage a number of times during one complete operation of this mechanical movement, the number of times being immaterial and governed eX- clusively by the timing mechanism not shown. The lever 14 is connected with a rock shaft 15 which carries an arm 16 pivoted to a link 17. The link 17 is provided with a head 18 having a slot 19 formed therein which embraces a pin 20 carried rigidly by a lever 21. The 'lever 21 is pivoted at 22 and at its end opposite the pin 2O is pivotally connected with the link 23 which in turn is pivotally connectedwith the foot clamp 11. A spring 24 is provided which tends to draw the lever 21 to lower the foot clamp 11. The pivot pin 22 is carried by an arm 25 which is pivoted to the frame 10 as at 26.

The arm 12 carries a link 27 which in turn carries a rigid head 28Hhaving a slot 29 which also embraces and moves slidably upon the pin 22. The head 28 is connected with a link 30 through any approved formyof universal joint as shown at 31 and operates any mechanism as the ratchet 32. Pivoted upon the head A28 at 33 is a detent 34 shaped as a bell-crank lever, one end being positioned in the path of movement of the pin 35 carried by the head 18 and the other end in the'path of movement of the pin 22. rlhe detent 34 is held in normal position yieldingly by a spring 36 with a stop 37 positioned to limit the movement of the detent in one direction so that one end of such detent is positioned to be engaged by the pin 22 to form a fulcrum therefor.

In operation it is assumed that the roller 13 carried by a carriage is to reciprocate a predetermined number of reciprocations during the complete operation of this mechanical movement and that at the rst reciprocation it isV desirable to lower the foot clamp 11. When, therefore, theV roller 13 moves in the direction indicated by the arrow in Fig. 1 it permits the pin 20 to move in the same direction under the impulse of the spring 24 to lower the foot clamp in the direction indicated by its arrow. It is obvious, however, that if the parts remained as shown in Fig. 1 when the carriage moves in its return, the roller 13 would engage the lever 14 and lift the foot clamp. This is not desired. To prevent this lifting movement the head 18 advances until the pin 35 engages the detent 34 which throws this detent out of engagement with the pin 22. This permits the pin 22 to ride along the slot 29 under the impulse of the spring 21 to the position shown in dotted lines in Fig. 3. It is thus seen that the fulcrum of the lever 21 is oating and that the head 18 may move under the impulse of the roller 13 as many times as may be desired without operating the link 23 or the foot clamp 11. After a predetermined number of reciprocations of the roller 13 the arm 12 is actuated to be lowered which by reason of its pivoting` to the link 27 throws the head 28 to the dotted position shown at Fig. 4. This changes the relation ofthe head 28 ,and pin 22 to the position shown in Fig. 1 relative only to the slot 29. After the movement of the head 28 to this position at the next reciprooation of the roller 13 the link 17 is moved to permit the spring 36 to throw the detent in the rear of the pin 22 as shown in full lines at Fig. 4. The carriage now stops its reciprocation for a period and asthe arm 12 is raised it is obvious that the pin 22 will be moved from the dotted position in Fig. 4 to full line position at Fig. 1 andthe pin being held against movement by the head 18 the resulting movement will be the movement of the lever 21 and the consequent movement of the link 23 and the 'raising of the foot clamp 11. As the arm 12 moves downwardly to move the head 28 forwardly the link also simultaneously operates the ratchet 32. It will, therefore,

be seen that the foot clamp is initially low ered by the movement of the lever 14 but after such lowering the movement of the lever 14 has no further effect upon such foot clamp it remaining in clamping position. It will also be apparent that the foot clamp is raised by the raising of the arm 12 after completing its operation, the lever 14 being then held stationary bythe roller 13 which has ceased its reciprocation.

I claim:

1. In a mechanical movement, a pivoted arm; a lever fulcrumed upon the extremity of the arm; a head slidably mounted relative tothe fulcrum; a detent carried by the head and adapted to engage the fulcrum and retain it at one extremity of the head; a link adapted to first vrelease the lever and neXtto actuate the detent to release the yfulcrum; and-means to reciprocate the head.

2. In a mechanical movement, an arm pivoted at one end and provided with a pin at its opposite end; a lever fulcrumed intermediate its ends upon'the pin; a head pr0-V vided with a slot slidably mounted upon the pin; a link slidable relative to one end of the lever; ay detent mounted upon the head and adapted to engage the pin and yform a fulcrum for` the lever; a lug carried by the link adapted lto engage the detent to throw it out of engagement with the pin; and a spring adapted to move the pin in the slot of the head.

3. In a mechanical movement7 a head adapted to reciprocate and provided with a slot; a fulcrum slidably mounted in the slot; a lever pivoted to oscillate upon the fulcrum; a detent carried'by the head and adapted to engage and pivot'the fulcrum;

and Va sliding link engagingthe lever Yand forming a fulcrum for one end thereof and carrying Va lug adapted to en'gageand release the detent.

yIn testimony whereof I a'iX my signature in presence of two witnesses.
